4 Claims. (Cl. 2li-@11) This invention relates to window structures ofthe sashless type.

A general object of this invention is to provide a sashless window whichis simple in structure, economical to produce, convenient and effectivein operation, and lfully in accordance with present day buildingstandards.

Another object is to provide a sashless window having an improved handlestructure for opening and closing the window, such handle structurebeing easy and inexpensive to apply to the window, and `having a fullypositive locking means associated therewith.

Another object is to provide a sashless window having improved glasspanel bearing channels.

Another object is to provide a sashless Window having improved panelclamping means.

The invention will be described with reference to the accompanyingdrawing, in which Figure 1 is a side elevation of -a window structure inaccordance with the invention,

Figure 2 is a cross-sectional View ure l,

Figure 8 is a side elevation of the handle means,

Figure 9 is a partial sectional plan of an alternative locking means andhandle, and

Figure l0 is a side elevation of the locking means and handle of Figure9.

In the drawing, the window assembly illustrated comprises a wood frame 1having sill 2, jambs 3 and 4, and head piece 5. Two pairs of sashlessglass panels 6 and 7 and 8 and 9 are mounted in the frame. Since panels8 and 9 constitute the double or storm window portion of the structureand since their mounting in the frame is substantially identical withthat of panels 6 4and 7, only the mounting for the latter panels will bespeccally referred to in the ensuing description.

The sill 2 has a groove or channel 10 for reception of the edge portionof glass panel 6. Groove 10 has a rearwardly oifset portion 11 forreception of the edge portion of glass panel 7.

It will be apparent that, in the normally closed posi- 'on of panels 6and 7, their meeting edge portions will overlap as clearly shown inFigures l and 2. Preferably, groove 10 is provided with channel strips12 and 13 of suitable semi-rigid plastic composition such aspolyethylene, such strips being in longitudinal alignment with their endedges in substantial abutment. Strip 12 extends over the bottom sidesurfaces of offset portion 11 and the ad- `on line 2-2 of Figof saidpanel and locking vshoulder 15 defining the end of offset groove portion11.

The channel strips 12 and 13 provide smooth wear resisting surfaces forengagement with the glass panels 6 and 7 and ensure ease of slidingmovement of the panels as well as effective sealing engagement of thepanels with the sill during the life of the window. Preferably, thegroove 10 and portion 11 `are provided with corner notches 10a toreceive the edge portions of strips 12 and 13 and thus provide retainingmeans therefor. Preferably also, the bottom surfaces 12a and 13a of thechannel strips are inclined downwardly from back to front inorder tourge the glass panels into close fitting engagement.

Rib 14 terminates inwardly in slightly spaced relation to the adjacentedge of glass panel 6 in the closed position thereof and its end edgesurface 16 is inclined and bevelled, as shown, whereby, when suchadjacent edge of glass panel 6 engages the same during opening movementof the panel, the surface 16 will exert :a camming action on the panel 6to move it out of engagement or into loose engagement with panel 7 andthus permit easeof opening movement.

Head 5 is also provided a complementary groove 17 to receive the upperedge portions of panels 6 and 7. A portion of groove 17, as indicated at18, is of suliicient depth to permit raising of each panel 6 and 7 asuicient distance to disengage it from groove 10 and thus permit removalof the panel from the frame.

Each jamb 3 vand 4 is provided with a groove 19 communicating withgrooves 10 and 17 for reception of the side edge portion of a respectivepanel 6 and 7. Preferably, each groove 19 is provided with aweatherstripping channel 20 formed of rubber, resilient plasticcomposition or the like. The channel 20, las shown, has a rib 21extending inwardly from its bottom wall.

Means for importing sliding opening and closing movements to panel 6comprises a handle structure 23. Handle structure 23 includes a U-shapedmember 24 arranged to embrace an outer edge portion of panel 6. Themember 24 is mounted on the panel by means of a plastic strip 25 whichfirmly bonds the member 24 to the panel. The inner surfaces of member 24may be serrated as indicated at 26 to firmly lbond the strip 25 thereto.rThe member 24- has a manually engageable handle 27 projectingtherefrom. Member 24 may be formed of metal, plastic composition orother suitable material.

Means for clamping the panels 6 and 7 in closed or partially openposition comprises a clamping bracket 28 having ya base plate 29adjustably mounted on sill 2 as by means of screws 30 extending throughslots 31 in the plate 29. Pivoted at 32 to the base plate is a clampingknob 33 having a projection 34 provided with a nonmetallic tip 35 forengagement with the panel 6. The tip 35 may be made of plasticcomposition such as polyethylene and is provided with a rearwardlyextending shank 39 which is rigidly and frictionally seated in a socket40 in knob 33. The knob 33 has manually engageable curved surfaces 36for easy manipulation thereof. A stop 37 carried by the base plate isengageable by knob 33 to define the locked position thereof. It will beapparent that, by rotating knob 33 to swing its tip 35 out of engagementwith the glass panel, the latter is freed for sliding movement. To lockpanels 6 `and 7 together, it is simply necessary to swing the knob toapply pressure on panel 6 and thus press panel 6 into clampingengagement with panel 7.

The sill 2 is provided with the usual drainage passages 38.

Means for positively locking the panels 6 and 7 in closed position isassociated with the handle structure and comprises a latch 41 pivotallymounted on jamb 4 by means ofa bracket 42 which has a stop 43 dening theopen position of the latch. The latch is niounted'in 'lat erallyopposite relation to the handle member 24 and has a handle portion 44and end portion 45 for engagement with a shoulder 46 on member 24. Whilethe shoulder 46 is shown as projecting from the body of member 24, itwill be understood that it may, if desired, be recessed within the body.

Referring to Figures 9 `and 10, `alternative means for locking panels 6and 7 in closed position comprises a spring-loaded latch 47 mounted in'bracket 48 secured to jamb 4. Latch 47 is engageable by a shoulder 49on member 24. A lever 50 pivotally mounted in bracket 48 is connected tolatch 47 for manual release of the same.

2. A sashless window structure as deiined in claim l, said channel striphaving a longitudinally extending rib projecting outwardly from theexterior surface of each side wall thereof and laterally opposite thebottom wall thereof, said groove having notches each receiving one ofsaid last mentioned ribs.

3. A sashless window structure as dened in claim l, said single pathhaving a greater width than each of said rst-mentioned parallel paths.

4. A sashless window structure as defined in claim 1, said channel stripcomprising two sections in end-to-end abutting relationship, said ribbeing located in one onlyl of said sections and terminating in spacedrelation tot the end thereof abutting said other panel.
